Portable dome light



April 9, 1957 G. s. HESlsE PORTABLE DOME LIGHT Filed Feb. 14, 1956INVENTOR -7G1berTJHesse Attorney United States Patent PORTABLE DOMELIGHT Gilbert S. Hesse, Saint Calixte de Kilkenny, Quebec, CanadaApplication February 14, 1956, Serial N o. 565,426 1 Claim. (Cl. 24U-59) This invention relates to portable lights and more specifically toelectrical lights, to mark the position of a person.

While similar lamp structures of this general character were developedoriginally for use by miners, they have gone into rather general use inother lines.

In lamps of the commercial form power is supplied by dry cells orstorage batteries which usually are slung from the wearers belt or arecarried on some other part of the person. The lights used are typicalsearch lights and `iedly attached to the source or detachable andconnectable by means of separate extensions, sometimes with specialattachments to be supported by special sockets, with a clamp on a beltor on the cap, or might be held in the mouth as disclosed in the U. S.Patent 2,299,467.

The demand for small portable lights is well known for use of miners,hunters and others, but all devices used at the present time providesearch lights with more or less narrow beams, which are primarily`designed for work, or manipulation of tools or weapons. Under certainconditions it is important to mark the position of a person clearly andto provide a safety light in these cases, wherein a pure reector asalready known for the same purpose is not suitable. Reflectors for thesame reason are useful only on highways, if a strong light beam of theapproaching vehicle can be applied to obtain -an effective reflection.In many other cases as du-ring hunting in dense forests, in adits or inpropecting in caves no other light sources are on hand for reflections,therefore self contained portable lights have been in use up to now,which must be carried, not leaving both hands free for othermanipulations.

One object of this invention is the provision of a portable lightassemblage including a container in which the bulb itself may be housedand which might be mounted in a position suitable for use, with .aconnection extending from the lamp to electrical energizing means arranged in a separate container.

Another object of this invention is the provision of a unit of thecharacter mentioned in which the cover of the container is provided witha clear plastic portion, or any suitable material, the lower portion ofthis container being adapted to be attached to a cap, a helmet, orpinned to la shoulder piece.

A further object of this invention is the provision of -a portable lightof such a type that the light is visible in any direction.

Still another object of the invention is the provision of a portablelight unit including detachable means for the connection between sourceand light.

Other obvious features and advantages of this invention will be apparentfrom the following description ac companied by the drawings in whichcorresponding parts are designated by similar numerals of reference.

Figure 3 yis the protective cover of the bulb;

Figure 4 is the reflector with a socket;

Figure 5 is the base with a male plug and a pin;

Figure 6 is a detail of the female plug with connector;

Figure 7 is a container for the electric source.

A base S contains a male plug 12 and a safety pin 2. In convex reflectorIl, is provided a socket 16 with connections to the mentioned plug 12(not shown) in the drawings. Inserted in this socket 16 and held inconducting connection is an electric bulb 17, which is sur rounded andprotected against breakage by means of a transparent cover 3. A threadedpart 18 of this cover 3, is engaged in a corresponding thread 15, of thebase 5. A separate connector with a female plug 8, conductors 6 and yascrew-in member 9, leads through a disk 13, of insulating material. Thepurpose of this disk 13, is to secure the screw-in member 9, in thecorresponding base of a container 7 for dry cells lil and lila. Thisdisk 13, is held in its correct position by means of a threaded cover14.

In use and application of this invention the light is pinned to the capor on the shoulder of the person by means of the safety pin 2. Torelieve the connector 6, from any tension, `and to avoid tipping of thelight the clamp 1, has to be set in a suitable position, as soon as theplugs 8, and l2 have been connected. The container 7, with the batteriesmight be carried in a pocket, so that the 'switch 1l is easily operable.

According to the individual conditions for the use of the describedsafety light, the color of the transparent cover 3 might be selected. lnmost cases a yellow or Iamber cover will be the most suitable one, butany other color can be used if preferred by certain reasons.

From the above disclosure it will be seen that the safety light asdescribed is a useful and efficient means to indicate the position of aperson under dangerous conditions. Although certain speciiic embodimentsof the Iinvention have been shown for purposes of illustration, it isevident, that the light with the connector and the battery may bemounted in any suitable manner and that various changes andmodifications in size, proportion and supplying electric energy may bemade in the above specilically described structure without departingfrom the spirit of the invention, the changes and modifications beingrestricted only by the scope of the following claim.

I claim:

A portable light comprising a circular base having external screwthreads around its upper end, the bottom of said lbase being recessed, afastener mounted in the recess of said base for attaching the base tothe clothing of a person, a convex reflector mounted on the top of saidbase having a lamp socket in the top thereof, a lamp bulb mounted in thelsocket of said reflector, a dome-shaped transparent cover mounted onsaid base in covering relation to `said lamp bulb and reflector havinginterior screw threads at its lower end for engaging the screw threadsof said base, and lan electrical plug mounted in the side of said basehaving connection with the socket of said re- Hector.
